Mystery solved.
The scale of the map is misleading.
The two blue dots 'In Liverpool' are actually in an area between Old Halewood Village, Hale Village and Hale Bank and Bickerstaffe to the north.
The survey, done in the mid to late 50s was compiled in the early 60s when these places were rural and 'isolated' from the major surrounding industrial conurbatons due to static population movement.
The subject interviewed were all 'old' and male, so learned the language of their district in Victoria's day
Which is why nobody will have heard the word 'teem'...it was probably dying out when recorded.
